Scheduling a PL/SQL Program?

I have a PL/SQL block that I need to execute after midnight every night to update the content of a table. Should I embed this as a subprogram directly into the database (I currently run it from SQL*Plus, but have problems getting it to run as a cron job)? If I do that, how do I trigger it at a given time each day?

Thanks,
